I am using a rifle with a weaver style rail and weaver style rings and am unable to switch to Leupold turn in mounts with the windage screw. I am going to attempt to shim this scope to see if I can make it work. I know shimming isn't the best route but this is the path I would like to try first. Currently if I move the scope ALL the way to the right I am just at the center of the target at 50 yards. So when shimming do I add shims to the front or rear ring? Also for my issue do I need to add them to the left or right side? Thanks in advance for the help. I am really hoping I will be able to fix this issue this way!
